I am confused by the existence of both 'network' and 'subnet'. According to v2 API spec[1], subnet is introduced to support IPAM capabilities. Can anyone elaborate it to me? For example, what is the benefit of creating 1 network and 2 subnets by comparison with creating 2 networks that implicitly has one and only one subnet for each?
I do know that the original network did not support IP overlapping before subnet is introduced. But it is just an implementation issue, right? Thanks, Zhidong [1] https://wiki.openstack.org/wiki/Quantum/APIv2-specification
